BEVEL-G u DE FOR SAW-TABLES.

SPECIFICATION forming part of Letters Patent No. 453,893, dated June 9,1891.

Application filed August 5 1890.

To all whom it may concern.-

Be it known that I, H BURTON SMITH, a citizen of the United States,residing at Philadelphia, in the county of Philadelphia and State ofPennsylvania, have invented a new and useful Bevel-Guide for Saw-Tables,of which the following is a specification.

This invention relates to bevel-guides for saw-tables; and it has forits object to provide a device of this class which shall be simple inconstruction and eflicient in operation, and which shall take the placeof the tilting sawtable now usually employed for beveled work, and whichis objectionable on account of the expense of the machine.

Vith these ends in View my invention consists in the improvedconstruction, arrangement, and combination of parts, which will behereinafter fully described, and particularly pointed out in the claims.

In the drawings hereto annexed, Figure 1 is a plan View of a saw-tablehaving my i1nproved bevel-guide attached. Fig. 2 is a perspective Viewof the bevel-guide detached. Fig. 3 is a sectional View taken on theline 3 3 in Fig. 1. Fig. 4 is a sectional detail view of thebevel-guide.

Like numerals of reference indicate like parts in all the figures.

1 designates the saw-table, which is provided with a box or bearing 2fora rod 3, carrying the ordinary straight guide 4. I

5 designates a block provided with laterallyeXt-ending wings or flanges6 6. This block is secured detachably to the straight guide 4 by meansof bolts 7.

Through the wings or flanges 6 of the block 5 extends a shaft 8,provided at one end with a thumb-nut 9. 1O designates a guide-board, thelower inner side of which is connected with the flanges 6 by means ofpivoted links 11. Slotted links 12 are connected pivotally to the innerside of the guide-board 10, near the upper edge of the-latter, and theslots in the said links work over the ends of the longitudinal shaft orrod 8, that extends through the flanges 6. It will be seen that by thismethod of connecting the guide-board with the flanges 6 it may bereadily adjusted to any desired angle or inclination, and may be SerialNo. 361,056. (No model.)

secured at such adj ustmcnt bysim ply tightening the thumb-nut 9. j

The guide-board 10, which practically constitutes the bevel-guide, isprovided with right-angled brackets 13, secured in grooves or recesses14 in its upper side. The outwardly-extending arms 15 of said bracketsare provided with slots 16, the' outer endsiof which terminate in eyesor enlargements 17. Guide-slats 18, having transverse grooves 19 for theaccommodation of the arms 15 of the angle-irons, are secured to thelatter by means of set-screws 20, the heads of which work in the slots16, which thus admit of the convenient adjustment of said slats. Thelatter may also be conveniently removed by simply loosening theset-screws and moving the slats in an outward direction, when the headsof the set-screws may pass out through the eyes 17 at the outer ends ofslots 16.

The edges of the supporting-slats 18 are to be beveled, as shown at 22,so as not to interfere with the saw at any position to which the guidemay be adjusted, and the lower slat 18 may have a slot 23, whereby thesaw can be operated therethrough nearer the angle than in the openingbetween the slats.

The operation of my invention and its advantages will be readilyunderstood from the foregoing description, taken in connection with thedrawings hereto annexed, by those skilled in the art to which itappertains. The slats 18 are to be adjusted on opposite sides of thesaw, and the said slats, together with the guide-board 10, form atrough, in which the material to be operated upon may be accuratelyguided past the saw. The guideboard 10 may be readily adjusted by meansof the slotted links 12 to any desired position, and the position of thesaid board with relation to the saw may also be gaged by adjusting therod 3 of the straight guide in its boxing, where it is secured in theusual manner by a set-screw.

It will be seen from the foregoing that my improved bevel-guide forms acomplete attachment, which may be readily applied by bolting it. to thestraight guide which is found upon any ordinary saw-table.

The construction of the device is exceed ingly simple, and it may befurnished at an expense very much less than that of a tilting saw-table,which it in every respect supplants.

Having described my invention, What I claim is 1. In a bevel-guide, thecombination of the guide-board, means for tilting and adjusting thesame, the angular brackets secured to the guide-board, andthesupporting-slats attached to said brackets, substantially as setforth.

2. In a bevel-guide, the combination of the guide-board, means fortilting and adjusting the same, the angular brackets secured to theguide-board, and the supporting-slats secured adj ustably to the saidbrackets, substantially as set forth.

3. In a bevel-guide, the combination of the guide-board, the angularbrackets secured to the same and having outwardly-extending slottedarms, and the supporting-slats having set-screws whereby they aremounted adjustabiy upon said arms, substantially as set forth.

4. In a bevel-guide, the combination of the adjustable guide-board, theangular brackets secured in recesses in the-outer side of said ofslotted links working over the rod having the thumb-nut, the angularbrackets secured to said guide-board, and the supporting-slats securedadj ustably to the outwardly-extending arms of said brackets, the Wholeadapted to be connected detachably with the straight guide of anordinary saw-table, substantially as and for the purpose set forth.

In testimony that I claim the foregoing as my own I have hereto afiixedmy signature in presence of two Witnesses.
